How should chemicals be stored in the lab?

• A. In random order
• B. By chemical hazard level only
• C. Alphabetically
• D. According to chemical properties & classification

Answer: (D)

Storing chemicals by their properties and classification keeps incompatible substances apart and matches storage conditions to each material’s safety needs. This approach groups chemicals by how they react and what hazards they pose—flammables, oxidizers, acids, bases, and reactive substances—so that the right cabinets, temperatures, and containment are used, and so that acids are kept away from bases, and oxidizers are kept away from fuels. It also guides considerations like moisture sensitivity, light sensitivity, and ventilation, so that reactive or stored-in-dark compounds aren’t harmed by improper environments. If you stored by random order, by hazard level alone, or alphabetically, you’d lose track of which chemicals can safely coexist or how they must be secured, increasing the risk of spills, fires, or dangerous reactions.
